I got the same behavior when I did
?save.image

in a new run, i.e., without having asked for help.search().
So maybe it's the "." that's the problem.  Is that a known issue?

?lm also produced the error after the help.search() request, so it is
not only "." commands that are affected once the problem kicks in.
